Imaging findings
Chest x-ray revealed a well-defined tubular opacity superior to the aortic arch, in connection with it, without significant tracheal displacement. CT confirmed this as an aberrant right subclavian artery, originating from the left side of the aortic arch.
Key takeaways
Aberrant right subclavian artery (Arteria Lusoria) is a common aortic arch anomaly that can be seen as a tubular opacity on chest radiographs connected to the aortic arch, often without causing symptoms or tracheal compression.
